Course Objective

This course overviews the wastewater treatment engineering approaches to protecting water quality with an emphasis on fundamental principals. Theory and conceptual design of wastewater treatment processes will be discussed. Lectures cover the physical, chemical, and biological processes as indicated in the course syllabus. It covers the development of relevant theoretical concepts up to the point where, in homework and example problems, they can be applied to practical applications. The course delves into design and operation of wastewater treatment processes.

Learning Outcomes of the Course Unit

1   Definability of preliminary design and operation of the wastewater treatment unit operations
2   Definability of which wastewater treatment processes can be applicable for which contaminants
3   The ability of designing of wastewater treatment processes: physical, biological, chemical, and advanced units
4   Describability of operational problems in wastewater treatment plants
5   Definability of the conceptual elements on the management of wastewater treatment
